+------
+
+In Linux 2.6.31+ the i386 kernel needs to run the mcelog utility
+as a regular cronjob similar to the x86-64 kernel to process and log
+machine check events when CONFIG_X86_NEW_MCE is enabled. Machine check
+events are errors reported by the CPU. Processing them is strongly encouraged.
+All x86-64 kernels since 2.6.4 require the mcelog utility to

+When: 2.6.32
+Why: Remove the old legacy 32bit machine check code. This has been
